Khan and Brook will finally collide this weekend and the former will have Pound for Pound superstar Crawford in his corner.
The American stopped both Khan and Brook - most recently of Brook in 2020 but is supporting Khan and will be at the AO Arena in Manchester alongside trainer Brian "BoMac" McIntyre.
"It's great that [Crawford] is here," Khan said. "He is pound-for-pound one of the best.
"He has a lot of fans in the UK.
"He beat Brook and is now on my team - that will definitely affect Brook and put him on a low.
"My game-plan is to stick to what BoMac, Crawford and the team tell me to do.
"I'll catch him with good, clean shots. Automatically you will see Brook want to give up. I have the power and the speed."
Crawford says 'Khan is ready'
Crawford stopped Brook inside four rounds in what was an exciting bout while it lasted.
Asked if he has passed on any tips to Khan ahead of the all-British blockbuster, Crawford said: "We have different styles. Amir is fast, he likes to box a lot. Two different styles.
"What he is working on against Brook is different to what I worked on. It is not the same game-plan."
"I can't speak for another man," Crawford added when asked if Brook can bounce back from his defeat to him.
"That was a great fight. To me, he still had a lot left in him. But I caught him with a good shot.
"I'm here to support Amir. He has been in training with myself and my coaches. So I am just supporting a friend.
"Amir is ready. He has done everything that he needs to do.
"It should be a great fight.
"We, as fighters, lose sight of things that we should and shouldn't be doing. The most important thing in the game-plan is to be himself, to stick to what is working."
